remove: add progress support

remove: queue warnings until after status messages (issue5140) (API) Before this change, warnings were interspersed with (and easily drowned out by) status messages. API: abstractsubrepo.removefiles has an extra argument warnings, into which callees should append their warnings. Note: Callees should not assume that there will be items in the list, today, I'm lazily including any other subrepos warnings, but that may change. cmdutil.remove has an extra optional argument warnings, into which it will place warnings. If warnings is omitted, warnings will be reported via ui.warn() as before this change (albeit, after any status messages).

tests: include progress for test-remove

chg: allows default hg path to be overridden Before this patch, chg will fall back to "hg" if neither CHGHG nor HG are set. This may have trouble if the "hg" in PATH is not compatible with chg, which can happen, for example, an old hg is installed in a virtualenv. Since it's very hard to do a quick hg version check from chg, after discussion in IRC with smf and marmoute, the quickest solution is to build a package with a hardcoded absolute hg path in chg. This patch makes it possible by adding a C macro HGPATH.

chg: define PRINTF_FORMAT_ for non gnu C compiler Before this patch, if __GNUC__ is not defined, PRINTF_FORMAT_ will not be defined and will cause compilation error. This patch solves the issue by making sure PRINTF_FORMAT_ is defined. It allows chg to be compiled with tcc (http://bellard.org/tcc/) by: tcc -o chg *.c

chgserver: drop bundle.mainreporoot config Before this patch, although chgserver drops repo object by setting it to None, there is another side effect loading a repo: setting bundle.mainreporoot. This patch explicitly sets it to empty to undo the side effect. It will make chg pass test-strip.t.

chgserver: drop old hack to recreate ui on HGPLAIN change It's been superseded by config/env hash. A log message is simplified as we no longer need a diff of environment variables. Also, _loadnewui() is changed to require args since it can't copy old --config values without args.

graphmod: allow edges to end early Rather than draw an edge all the way to the bottom of the graph, make it possible to end an edge to parents that are not part of the graph early on. This results in a far cleaner graph. Any edge type can be set to end early; set the ui.graphstyle.<edgetype> parameter to the empty string to enable this. For example, setting the following configuration: [ui] graphstyle.grandparent = : graphstyle.missing = would result in a graph like this: o changeset: 32:d06dffa21a31 |\ parent: 27:886ed638191b | : parent: 31:621d83e11f67 | : o : changeset: 31:621d83e11f67 |\: parent: 21:d42a756af44d | : parent: 30:6e11cd4b648f | : o : changeset: 30:6e11cd4b648f |\ \ parent: 28:44ecd0b9ae99 | ~ : parent: 29:cd9bb2be7593 | / o : changeset: 28:44ecd0b9ae99 |\ \ parent: 1:6db2ef61d156 | ~ : parent: 26:7f25b6c2f0b9 | / o : changeset: 26:7f25b6c2f0b9 |\ \ parent: 18:1aa84d96232a | | : parent: 25:91da8ed57247 | | : | o : changeset: 25:91da8ed57247 | |\: parent: 21:d42a756af44d | | : parent: 24:a9c19a3d96b7 | | : | o : changeset: 24:a9c19a3d96b7 | |\ \ parent: 0:e6eb3150255d | | ~ : parent: 23:a01cddf0766d | | / | o : changeset: 23:a01cddf0766d | |\ \ parent: 1:6db2ef61d156 | | ~ : parent: 22:e0d9cccacb5d | | / | o : changeset: 22:e0d9cccacb5d |/:/ parent: 18:1aa84d96232a | : parent: 21:d42a756af44d | : | o changeset: 21:d42a756af44d | |\ parent: 19:31ddc2c1573b | | | parent: 20:d30ed6450e32 | | | +---o changeset: 20:d30ed6450e32 | | | parent: 0:e6eb3150255d | | ~ parent: 18:1aa84d96232a | | | o changeset: 19:31ddc2c1573b | |\ parent: 15:1dda3f72782d | ~ ~ parent: 17:44765d7c06e0 | o changeset: 18:1aa84d96232a parent: 1:6db2ef61d156 parent: 15:1dda3f72782d The default configuration leaves all 3 types set to |. This is part of the work towards moving smartlog upstream; currently smartlog injects extra nodes into the graph to indicate grandparent relationships (nodes elided).

graphmod: allow for different styles for different edge types Rather than draw all edges as solid lines, allow for using different styles for different edge types. For example you could use dotted lines for edges that do not connect to a parent, and dashed lines when connecting to a grandparent (implying missing nodes in between). For example, setting the following configuration: [ui] graphstyle.grandparent = : graphstyle.missing = . would result in a graph like this: o changeset: 32:d06dffa21a31 |\ parent: 27:886ed638191b | : parent: 31:621d83e11f67 | : o : changeset: 31:621d83e11f67 |\: parent: 21:d42a756af44d | : parent: 30:6e11cd4b648f | : o : changeset: 30:6e11cd4b648f |\ \ parent: 28:44ecd0b9ae99 | . : parent: 29:cd9bb2be7593 | . : o . : changeset: 28:44ecd0b9ae99 |\ \ \ parent: 1:6db2ef61d156 | . . : parent: 26:7f25b6c2f0b9 | . . : o . . : changeset: 26:7f25b6c2f0b9 |\ \ \ \ parent: 18:1aa84d96232a | | . . : parent: 25:91da8ed57247 | | . . : | o-----+ changeset: 25:91da8ed57247 | | . . : parent: 21:d42a756af44d | | . . : parent: 24:a9c19a3d96b7 | | . . : | o . . : changeset: 24:a9c19a3d96b7 | |\ \ \ \ parent: 0:e6eb3150255d | | . . . : parent: 23:a01cddf0766d | | . . . : | o---+ . : changeset: 23:a01cddf0766d | | . . . : parent: 1:6db2ef61d156 | | . . . : parent: 22:e0d9cccacb5d | | . . . : | o-------+ changeset: 22:e0d9cccacb5d | . . . . : parent: 18:1aa84d96232a |/ / / / / parent: 21:d42a756af44d | . . . : | . . . o changeset: 21:d42a756af44d | . . . |\ parent: 19:31ddc2c1573b | . . . | | parent: 20:d30ed6450e32 | . . . | | +-+-------o changeset: 20:d30ed6450e32 | . . . | parent: 0:e6eb3150255d | . . . | parent: 18:1aa84d96232a | . . . | | . . . o changeset: 19:31ddc2c1573b | . . . .\ parent: 15:1dda3f72782d | . . . . | parent: 17:44765d7c06e0 | . . . . | o---+---+ | changeset: 18:1aa84d96232a . . . . | parent: 1:6db2ef61d156 / / / / / parent: 15:1dda3f72782d . . . . . Edge styles can be altered by setting the following one-character config options:: [ui] graphstyle.parent = | graphstyle.grandparent = : graphstyle.missing = . The default configuration leaves all 3 types set to |, leaving graph styles unaffected. This is part of the work towards moving smartlog upstream; currently smartlog injects extra nodes into the graph to indicate grandparent relationships (nodes elided).

chgserver: use global ui instead of repo ui for dispatch.request.ui Before this patch, chgserver will use repo ui as dispatch.request.ui, while req.ui is designed to be global ui without repo config. Passing repo ui as dispatch.request.ui leads to repo.ui being incorrect, which can lead to unwanted results. For example, if the repo config has [extensions], it could affect which localrepository.featuresetupfuncs get executed and the repo may have an incorrect list of supported requirements. This patch changes _renewui to return both global ui and repo ui. The global ui is passed to req.ui, and the repo ui is used to calculate confighash. It will make chg pass test-largefiles-misc.t and test-requires.t, which are both related to repo requirements.
